Fig. 1-2-1-1  Number of persons newly received by public prosecutors offices for special act offenses (1949-2005)

  Fig. 1-2-1-1 shows the trend in persons newly received by public prosecutors offices since 1949 for special act offenses.
  The total number of special act offenses decreased sharply when the traffic violation notification system came into force in July 1968 and remained on the range of 2 million persons through 1975 to 1984. The number decreased sharply again due to the expansion of the scope of this system in 1987 and has generally been on a declining trend. Meanwhile, the number of special act offenses excluding violations of road traffic related acts has been increasing since 2001.
  Fig. 1-2-1-2 shows the percent ratio of persons newly received by public prosecutors offices for special act offenses excluding violations of road traffic related acts in 2005.
